A Year After WannaCry, And the Ransomware Still Harasses

Is your PC protected from the WannaCry ransomware? Apparently, millions of Windows systems are still vulnerable to a threat that actually isn't completely dead.

A huge swath of Windows machines beyond the globe — especially in China — accept yet to install patches that can ward off the set on'southward infection method, according to the security firm Kryptos Logic.

The findings come up every bit tomorrow marks the one-twelvemonth anniversary to the WannaCry outbreak, which infected computers across the globe and cost businesses billions in financial damages.

Fortunately, the attack was apace contained. A security researcher with Kryptos Logic famously activated a "impale switch" that effectively sterilized the attack.

Even so, WannaCry hasn't disappeared; the ransomware still lives on to this 24-hour interval.

When the kill switch was activated almost a yr ago, new WannaCry infections were essentially told to stand down. But this did nothing to save the Windows systems hitting with the ransomware during the initial outbreak, said Salim Neino, CEO of Kryptos Logic.

These untreated WannaCry machines will continue carrying the ransomware strain, indefinitely, unless the software onboard is completely reinstalled. Unfortunately, many of these untreated machines remain online, trying to spread the mostly harmless WannaCry infections to new computers, Neino said.

Information technology doesn't aid that millions of Windows of machines still remain vulnerable to the ransomware's infection method. Kryptos Logic has been monitoring activity to internet domain for the kill switch, and noted that traffic to it remains loftier.

Terminal month, over 104 million connection attempts were fabricated to the kill switch. These connection attempts were sourced to over ii.vii one thousand thousand unique IP addresses, about 25 to 45 per centum of which were based in China, where pirated copies of Windows vii accept been popular.

"If a single IP has 50k hits in a solar day, you lot can safely assume its non only i infected car behind that IP, it is probably a few hundred to thousands," Neino said in an e-mail.

The kill switch can forbid virtually of these attacks from becoming a total WannaCry infection, merely not all. In March, Boeing was mysteriously striking with the ransomware. How it happened isn't totally clear, but WannaCry can fully infect a PC if the automobile fails to connect with the impale switch.

Kryptos Logic has published a weblog post outlining some scenarios to how this might occur. But the cardinal takeaway is the need for system administrators to do what they can do to patch their systems. WannaCry is mostly harmless, just the ransomware'south infection method — originally sourced to a US cyberweapon — has already been incorporated into other hacking schemes.

The good news is that Kryptos Logic is offering a gratis service that tin can help enterprises identify any machines in their network that are existence bombarded by WannaCry infection attempts. You tin can find it hither. If yous're on Windows 10, you lot don't have to worry. The ransomware strain largely affects unpatched Windows 7 and Windows Server 2008 machines.
